FASTENING DEVICE.

Application filed June 5,

To all whom it may concern:

Be it known that CHARLES R. Nannie, citizen of the United States, residing at Nichita- Falls, in the county of l/Vichita and State of Texas, have. invented certain new and useful Iniprovementsv in Fastening Devices, of which. the following is a specification.

This invention relates to new and useful improvements in fastening devices.

'The object of the invention is to provide a fastening device in which a staple or other member may be frictionally held and wedged into place.

A further object of the invention is to produce a fastening device of a cheap and simple nature and which is particularly adapted for insertion in plastic structures, such as fence posts and the like.

Another object of the invention is to provide means for fastening fence wires to plastic or metal posts, which when broken may be replaced without cutting out the post and which will act under conditions similar to those of an ordinary staple driven into a wooden post.

A. structure designed to carry out the invention together with other novel features will be hereinafter described.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is a front elevation of a fence post having wiressecured thereto with devices constructed in accordance with my invention,

Fig. 2 is a side elevation of the same, the post having portions broken away to show the fasteners,

Fig. 3 is an enlarged sectional detail of one of the fasteners,

Fig. 4 is an end elevation of one of the fasteners,

Fig. 5 is a side elevation of one of the bar rels, and

Fig. 6 is a sectional detail showing a modified form of staple.

In the drawings the numeral 10 designates a tubular barrel having lugs 11 upset on opposite sides of one end and bent outwardly, substantially at right angles. The end carrying the lugs constitutes ahead.

A short distance from the other end of the barrel tongues 12 are upsetinwardly from the barrel and have their inner ends in con- 1923. Serial No. 643.564.

tact, thus forming an internal wedge. At the intersection of the tongue and the barrel a sharp angle is avoided by a gradual bend.

A staple 13 having its ends reduced and spread apart inserted in the barrel. The staple is driven in so that the eye 1%. is re ceived in the slots 15 provided when the lugs are upset. When the spread ends of the staple encounter the wedge. they will be separated and guided outwardly over the tongues. The ends of the staple will pass through the openings in the. side of the barrel and strike the side wall of the hole in which the barrel is inserted.

When the ends of the staple encounter the side walls they will be bent parallel to the barrel and directed rearwardly, thus wedging between said side walls and the barrel.

In Fig. 6 I have shown a modified form of staple in which the outer sides or faces of its ends are provided with serrations or barbs 16. These will bite into the side walls of the hole and more securely hold the staple in place.

In manufacturing the fasteners the barrels may be cut from a length of tubing of the proper diameter and the barrels punched to provide the lugs 11 and the tongues 12. Where they are to be used in a concrete post the latter is cast with holes 17 therein at the elevation at which it is desired to fasten. the wires.

The barrels 10 are inserted in the holes with their heads outward. The wires are threaded through the staples 13 by spreading the latter and forcing them over the wires or the staples may first be inserted and fastened in the barrels. The staples are driven into the barrels just like a staple is driven into a wooden post. The ends of the staple being slightly spread apart will be split by the wedge formed by the tongues and passed through the holes in the barrel. The ends of the staple will be bent parallel to the barrel by the side walls of the hole 17 and as these ends are tapered, they will be wedged between said side walls and the barrel. A final tap on the eye 1 1 with a hammer will drive the staple to its seat.

Where the modified form of staple with the serrations 16 is used, a more secure fastening will be had. The staple may be withdrawn by using the claw of a hammer and pulling it in much the. same way as a staple is withdrawn from a wooden post. If a staple should break 0d and the barrel cannot be withdrawn, it may be drilled out and a new fastener inserted without defacing the post.

Various changes in the shape and size of the parts as well as modifications and alterations may be made within the scope of the appended claims.

What I claim, is:

1. In a fastening device of the character described, a barrel having a pair of outwardly directed lugs and slots at its head, an internal wedge in the opposite end of the barrel, said barrel having openings on opposite sides of the Wedge, and a staple driven into the barrel and having its ends split by said wedge and projecting through the openings for engagement with the side Walls of the hole in which the barrel is inserted.

2. In a fastening device of the character described, a tubular barrel having outwardly upset lugs and slots at its head and inwardly upset tongues near its inner end, the

tongues being bent together to form an in ternal wedge, the barrel having openings opposite the tongues, and a staple having an eye seated in the slots of the barrel and its ends spread apart by the tongues and extending through the openings.

3. The combination with a plastic structure having an opening therein, of a tubular metallic barrel fitting loosely in said opening, the said barrel having an internal wedge with openings on each side thereof, and a staple driven into the barrel having its ends spread apart by the wedge and directed through the said openings, the ends of the staple which project from the barrel being bent parallel thereto and wedged between the barrel and the side Walls of the hole.

In testimony whereof I affix my signature.

CHARLES R. NALLE.
